Rusty,
The developer has submitted revised sidewalk plans for this park. They say they received Parks & Recreation
Advisory Board approval back at the August 12th meeting. I looked up the agenda and saw it on there but I
wanted to confirm the Board was okay having those improvements count as a credit toward their parkland
dedication fee requirements. Let me know.
Thanks,

Development Fee, the proposed park site plan needs to be approved by the Parks &
Recreation Advisory Board.
Noted. The Site Plan was approved on August 12, 2014.
2. According to the above section, if the land has been dedicated to the City, the developer is
to post payment and performance bonds to guarantee the work and payment to
subcontractors.
Noted.
3. Revise the Vicinity Maps to reflect the project location instead of Phase 108.
The Vicinity Map has been revised.
4. Please note that any changes made to the plans that have not been requested by the City of
College Station must be explained in your next transmittal letter and "bubbled" on your
plans.

estimate for work in City Parks.
Noted.
2. Please modify the sidewalk so the drainage paths are contained within the park area.
Private fences will likely block the drainage paths and no drainage easement currently exists
to preserve the drainage paths.
The alignment of the sidewalk was changed to allow drainage to stay out of the
residential lots.
3. Please show the location of the drainage easements in the adjacent phase.
The drainage easements are shown on the plans.
4. Please show safety end treatments on the drainage pipes.
Safety end treatments were added to the plans. Also, the engineer's estimate was
revised to include the SETs.

GENERAL DESCRIPTION AND LOCATION
This project consists of sidewalk and drainage improvements in Parks 5 & 8 in the Barracks II Subdivision in College
Station.
Location:
Description:
• Area:
• Land Use:
• Existing Land Use:
Parks 5 & 8 are located northeast of Phase 103 & 104 of the Barracks II
Development. The Barracks II Subdivision is a 108-acre development located
midway between Rock Prairie Road and Cain Road in south College Station. It
is bounded on the west by Holleman Drive South and on the east by Old Wellborn
Road.
2.16 Acres
Parkland
Vacant
• Land Description: The terrain slopes generally towards the northeast.
Primary Drainage Facility: Tributary B.3 of Bee Creek
Flood Hazard Information:
FEMAFIRM: #48041C0305F, Dated April 2, 2014
Floodplain: None of this phase of the development lies within the floodplain.
HYDROLOGIC CHARACTERISTICS
The existing site is cleared. The elevations range from 305 to 300, sloping generally in a northeasterly direction.
The runoff will be directed to culverts crossing the proposed sidewalk and will discharge into the existing stream
and the existing detention facilities on Lot 1, Block 28 Phase 300 of The Barracks II Subdivision. Ultimately, this
runoff flows into Tributary B.3 of Bee Creek.
GENERAL STORMWATER PLAN
The drainage plan for this development will involve the installation of storm sewer culverts, which will collect and
convey the runoff into the existing stream and then to the existing detention pond. The runoff that is collected by
the existing detention ponds will be discharged into tributary B.3 of Bee Creek.
The detention pond analysis and design for this phase is covered under the drainage report titled, "The Barracks
Detention Facility Design City of College Station, Texas, Dated July 2012" prepared by Kimley-Horn and as
modified in September 2013 by a revised design prepared by Kimley-Horn.
COORDINATION & STORMWATER PERMITTING
This project has a Notice of Intent filed with the Texas Commission for Environmental Quality. No other permits
are anticipated for this project.

inlet sizing.
The data presented in the Appendices indicates pipe sizes are in accordance with
the requirements of and the City of College Station.
The stormwater runoff from the Barracks II Subdivision was previously studied
and detention ponds were designed for the entire development including this
phase. See the drainage report titled, "The Barracks Detention Facility Design
City of College Station, Texas, Dated July 2012" and as modified in September
2013 by a revised design prepared by Kimley-Hom.

CERTIFICATION
I, Joseph P. Schultz, Licensed Professional Engineer No. 65889, State of Texas, certify that this report for the
drainage design for The Barracks II, Parks 5 & 8, was prepared by me in accordance with the requirements of the
Bryan/College Station Unified Drainage Design Guidelines for the owners of the property. All licenses and permits
required by any and all state and federal regulatory agencies for the proposed drainage improvements have been
issued.

GENERAL DESCRIPTION AND LOCATION
This project consists of sidewalk and drainage improvements in Parks 5 & 8 in the Barracks II Subdivision in College
Station.

Flood Hazard Information:
FEMAFIRM:
Floodplain:
Parks 5 & 8 are located northeast of Phase 103 & 104 of the Barracks II
Development. The Barracks II Subdivision is a 108-acre development located
midway between Rock Prairie Road and Cain Road in south College Station. It
is bounded on the west by Holleman Drive South and on the east by Old Wellborn
Road.
2.16 Acres
Parkland
Vacant
The terrain slopes generally towards the northeast.
Tributary B.3 of Bee Creek
#48041C0305F, Dated April 2, 2014
None of this phase of the development lies within the floodplain.
HYDROLOGIC CHARACTERISTICS
The existing site is cleared. The elevations range from 305 to 300, sloping generally in a northeasterly direction.
The runoff will be directed to culverts crossing the proposed sidewalk and will discharge into the existing stream
and the existing detention facilities on Lot 1, Block 28 Phase 300 of The Barracks II Subdivision. Ultimately, this
runoff flows into Tributary B.3 of Bee Creek.
\
GENERAL STORMWATER PLAN
The drainage plan for this development will involve the installation of storm sewer culverts, which will collect and
convey the runoff into the existing stream and then to the existing detention pond. The runoff that is collected by
the existing detention ponds will be discharged into tributary B.3 of Bee Creek.
The detention pond analysis and design for this phase is covered under the drainage report titled, "The Barracks
Detention Facility Design City of College Station, Texas, Dated July 2012" prepared by Kimley-Horn and as
modified in September 2013 by a revised design prepared by Kimley-Horn.
COORDINATION & STORMWATER PERMITTING
This project has a Notice oflntent filed with the Texas Commission for Environmental Quality. No other permits
are anticipated for this project.

Storm water runoff from this project will be collected by a storm sewer system and
will ultimately discharge into tributary B3 of Bee Creek or into the existing
stormwater detention pond. The location of the drainage areas for evaluation of
culvert sizing are shown on Exhibit A.

The software was used to compute pipe capacities, flow rates and velocities,
compute hydraulic grade line elevations, headwater elevations, gutter depth &
inlet sizing.
The data presented in the Appendices indicates pipe sizes are in accordance with
the requirements of and the City of College Station.
The stormwater runoff from the Barracks II Subdivision was previously studied
and detention ponds were designed for the entire development including this
phase. See the drainage report titled, ''The Barracks Detention Facility Design
City of College Station, Texas, Dated July 2012" and as modified in September
2013 by a revised design prepared by Kimley-Hom.

The culvert drainage system for Parks 5 & 8 of the Barracks II Subdivision will function within the requirements and
restrictions of the BCS Design Guidelines.
CERTIFICATION
I, Joseph P. Schultz, Licensed Professional Engineer No. 65889, State of Texas, certify that this report for the
drainage design for The Barracks II, Parks 5 & 8, was prepared by me in accordance with the requirements of the
Bryan/College Station Unified Drainage Design Guidelines for the owners of the property. All licenses and permits
required by any and all state and federal regulatory agencies for the proposed drainage improvements have been
issued.
